Components

(generated)

Component items:

• Neck sensory data (neck-sensory-data)
  • Neck - cutaneous receptors of low neck (neck-low-cutaneous-receptors -> LPC.PN.SG.UDRG): skin of medial infraclavicular region
• Neck flexors (neck-flexors)
  • Neck - scalenus anterior muscle (LPC.SC.VH.SAN -> neck-scalenus-anterior): elevates first rib, rotate the neck to the opposite side
  • Neck - scalenus medius muscle (LPC.SC.VH.SAN -> neck-scalenus-medius): elevate 1st rib, laterally flex (bend) the neck to the same side
  • Neck - scalenus posterior muscle (LPC.SC.VH.SAN -> neck-scalenus-posterior): elevate 2nd rib, tilt the neck to the same side
  • Neck - longus capitis muscle (LPC.SC.VH.SAN -> neck-longus-capitis): flexion of neck at atlanto-occipital joint
  • Neck - longus colli muscle (LPC.SC.VH.SAN -> neck-longus-colli): flexes the neck and head
  • Neck - rectus capitis anterior muscle (LPC.SC.VH.SAN -> neck-rectus-capitis-anterior): flexion of neck at atlanto-occipital joint
  • Neck - rectus capitis lateralis muscle (LPC.SC.VH.SAN -> neck-rectus-capitis-lateralis): sidebend at atlanto-occipital joint, takes care of flexing the neck
  • Neck - sternocleidomastoid muscle (LPC.SC.VH.VM -> neck-sternocleidomastoid): acting alone, tilts head to its own side and rotates it so the face is turned towards the opposite side; acting together, flexes the neck, raises the sternum and assists in forced inspiration
• Neck extensors (neck-extensors)
  • Neck - obliquus capitis inferior muscle (LPC.SC.VH.VM -> neck-obliquus-capitis-inferior-muscle): rotation of head and neck
  • Neck - obliquus capitis superior muscle (LPC.SC.VH.VM -> neck-obliquus-capitis-superior-muscle): extends head and flex head to the ipsilateral side
  • Neck - rectus capitis posterior major muscle (LPC.SC.VH.VM -> neck-rectus-capitis-posterior-major-muscle): ipsilateral rotation of head and extension
  • Neck - rectus capitis posterior minor muscle (LPC.SC.VH.VM -> neck-rectus-capitis-posterior-minor-muscle): extends the head at the neck, but is considered to be more of a sensory organ than a muscle
  • Neck - semispinalis capitis (LPC.SC.VH.VM -> neck-semispinalis-capitis): extend the head
  • Neck - splenius capitis muscle (LPC.SC.VH.VM -> neck-splenius-capitis): prime mover for head extension; can also allow lateral flexion and rotation of the cervical spine
  • Neck - splenius cervicis muscle (LPC.SC.VH.VM -> neck-splenius-cervicis): bilaterally: extend the head and neck, unilaterally: lateral flexion to the same side, rotation to the same side
